Seek advice from others where possible
Although it may be good to listen to your instinct as much as possible, it is important to also get advice from another person aside from yourself.
This way, not only are you learning on how to improve something you have done but it also allows you to think in different perspective from another person’s view.
Even if you may not like what you hear, you should simply listen and if you do not understand something remember to ask in a polite manner for the person to give you a more accurate answer. This way you can accept criticism and take it onboard graciously to help you to grow.
